THOMAS THEGDORE MERRIMAN AND BENJAMIN FRANK T N @EABT, OF CENTRAL POINT, OREGON.

Specification of Letters Patent.

Patented Mar. 5, 1912.

Application filed May 18, 1911. Serial No. 62?,932.

To all whom it may concern:

Be it known that we, THOMAS .l. Manni- MAN and BENJAMIN F. Pmn'r, citizens of the United $tates, and residents of Central Point, in the county oi Jackson andState of Oregon, have invented a new and Improved Vise, of which the following is a full, clear, and exact description.

.iilllOng the pr1nc1pal ob ects which the present invention has in view are: to provide ELVISQ attachable to. the anvil block or pedestal and operable in conjunction with adjusted to the' anvil block of ordinary construction.

One embodiment of the present invention is disclosed in the structure illustrated in the accompanying drawings, in which like characters of reference denote corresponding parts in all the views, and in which Figure 1 is 'a perspective view of an anvil and block therefor provided with a vise constructed and arranged in accordance with the present invention; Fig. 2 is a side view of the anvil, showing they block thereof equipped with a vise-constructed and arranged in accordance with the present iii-- vcntion, the vise being shown in operative holding position; Fig. 3 is a vertical section taken on the line ii -Pi in Fig. 2; and Fig. lis 2 horizontal cross section taken on the line 4l--4 in Fig.

The vise shown in the accompanying drawings is employed principally in thcop oration known as hot rasping. it is advau tagcous to rasp certain articles while the same are softened by the heat of the force,

to do which tin article is rested on the llat oi; the anvil. in the present instance the vise prmidcd'with a holding l'ooi fl, the

lower or holding surface \vhcrcol' is dowuturned to rest upon the tint oi the anvil 10. The an il 10, as in usual installations, is rested upon a pedestal or anvil hlocl; ll and there secured. 'lhe vise shown in the accompanying drawings is pivotally mounted upon the block 11, permitting thereby the change or replacement of the anvil. The foot flis disposed at the cud of a goose-mick 12 formed at the end of the swinging bar 15).

The bar 13 is shaped substantially as shown in Fig. 2 of the drawings, the body portion thereof being oltset to dispose the pivot. l-l beneath the operative position of the foot 9. .ln this manner is provided against exerting a rocking tendency upon the toot 9.

The bar 13 is connected. by means 01 the pivot M with a guide plunger 15. The plunger is mounted in a. socket lti through which it is reciprocated by means of a it'oot lever 17 to which it is opcratively connected by means of a link 1. The lever 17 is pivota'lly connected by means of a bolt 19 with the face plate 20. ,The face plate 20 is se cured by means oil fastening devices 21 upon the block 11.. The socket 16 is formed from a plate which is secured by means of rivets 2:2 upon the said plate. i

To cause the bar toassuine the vertical position above the anvil 10 there are provided the spiral springs at the free end of a. rocking arm 26. The arm 26 is rotatably mounted upon the pivot 14. A stop is formed by the arm to limit the throw of the plunger when drawn forward by the spring 2t. lJVhcn thus arrested the bar 13 assnn'ics the position shown in Fig. l, of the drawings.

hen the vise is properly installed on the block 11, as shown in the drawings, to

operate the same the smith, having placed on the anvil it) the article it which is to he rasped, which, in the present drawings is indicated as a horse shoe, he then places his toot on the trcadlc 52.55 and depresses the lover ll. The spring 52?} being connected with the lever 17 near the free end thereof, and

the link l8 bciup connected with the said lcvcr ucur tho fulcrum cud (hm-cot, the 0X- icnt oi the movement oi the spring 23 is proportionatclv rcalcr than the extent of the movement or the liulc 18. This operation :u-cclcratcs the swing: of the bar l3 about the pivot t l. causing; the said bar to assume the vertical position seen in Fig. 2. This operation is so timed to the movement of the link 18 that prior to the foot 9 reachin; the article A to be grasped, the said bar [3 has assumed vthe vertical position. The continued depression of the trcadle 28 by the smith now exerts a pull through the intermediary oi .thc link 18 and the plunger 15 upon the bar 13, the opc ti'on oi the plun nor 1:) being guided in the soclcct ill. The

co -24. The springs 23-24 are connected to the crab formed pressure-thus imposed upon the article A by the foot 9 is proportioned to the leverage of the lever 17 multiplied by the force applied at the tre adle 28. During the operation of the vise after the foot 9 has been seated upon the article A, the springs 2324 are expanded to accommodate the action of the lever 17 during the manipulation thereof to produce what may be termed the direct 1O pull on the bar 13. The leverage exerted by the lever 17 is varied by shifting the bolt 29 and the end of the link 18 connected thereby to the lever 17, to any of the perforations 30 formed in the said lever 17, as l5 shown in the drawings. When now in the course of operation the smith releases the treadle 28, the springs 2324 contracting lift the lever 17. The lift of the lever 17 raises the link 18 and bar 13 connected therewith to move the foot 9.from the article A. The center of gravity of the bar 13 being to the offset side of the body of the said bar,

or tothe right of the pivot 14 as viewed from Fig. 2 of the drawings, the bar 13 swings outward and drops to the position shown in Fig. 1 of the drawings, when the springs 2324 are relaxed. The pull of the spring 24 when the bar 13 assumes the horizontally extended position shown in Fig.

l rotates the arm 26 on the pivot 14 until the same is arrested, in which position it is held,

as shown in Fig. 1. The object of this construction is to prevent the arm 26 throwing past a vertical line drawn from the center of the pivot 14:, in which position, as will be seen, the pull of the spring 23 when the lever 17 is depressed would-serve to reverse. the desired operation as above described. In

the normal inoperative posit ion of the vise the springs 23-24 and the connecting arm 26 assume the position substantially shownin Fig. 1 of the drawings. I

Having thus describedourinvention,what we claim as new and desire to secure by Letters Patent is In a vise of the character described, afoot lever; a reciprocatory plunger; a socket for said plunger to guide the same; a link conmeeting said plunger and said lever,' said link connected with said lever at near the fulcrum thereof a' swingable arm pivotally lconnected with said plunger to normally rest" in a horizontal position; a spring opera tively connected with said swingable arm and said lever said spring being connected with said lever at near the power application endthereof; and an arm pivotally con nected to said plunger j/and said swingable arm at the junction thereof to holdsaid spring away from the pivot of said swingable arm and in operative position to move said swlngable arm. t

In testimony whereof we have signed our names to this specification in the presenceof
